Fatigue testing device for hose

The invention discloses a hose fatigue testing device, and relates to the technical field of fatigue tests.The hose fatigue testing device comprises a testboard, a swing mechanism and a bending mechanism, guide rods are symmetrically arranged on the testboard, a movable frame is slidably connected to the guide rods, and a right end clamping assembly used for fixing one end of a hose is installed on the movable frame; the right end clamping assembly is communicated with an air pump through an air conveying pipe, the swing mechanism is arranged on the left side of the test table and provided with a left end clamping assembly used for fixing the other end of the hose, and the bending mechanism is arranged on the test table and used for driving the tested hose to reciprocate to be bent. According to the device, the swinging mechanism drives the hose to swing back and forth, meanwhile, the bending mechanism conducts left-right reciprocating motion to bend the hose, the swinging and bending motion is conducted in a
